Not sure. I used it on/off for 4 hours. It last longer than my cell phone battery used as the music source.

The rechargeable batteries in mine last about 8 hours on a full charge with the radio playing. When I use alkaline batteries I get about 20 hours of play time.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

I get 7-8 hours of continuous audio out of mine! I listen to talk mostly, so maybe less bass = more battery? I dunno, but I've been through several pairs and always get, at least the 7 hours the nice lady inside the headphones says I'll get.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

I have had the battery on, outside at a party for 8 hours. The volume was just shy of full blast and it still had a lot of juice the next day. So even if you have it up full blast you get quite a long, long time outta the battery!!! Love my Melody...

I've had mine about a month now and I've used them for at least 20-30 hours while in the backyard on battery power. The sound is good, the range I am using is about 50 feet with minimal attenuating materials between (walls, doors, etc). I'm not sure how long the batteries will last. You can probably do the calculations based on average current draw and the capacity of C sized cells.

Approximately 8 and sometimes 10 hours if I leave them on and if I buy really good batteries. They are easy to turn off and on to save battery life and easy to change the batteries

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.

I see many have answered already. I get about 6-8 hours, then when it beeps in my ears I use a longer usb cable to charge them while using them. win.

I would say that mine has an average life of around 12 hours when its fully charged. There is no volume control on the actual speaker though, you have to control that through whatever device you are playing on it (phone, computer, etc)

With the 18v lithium-ion slim pack I get a solid 6-8 hours of radio from almost the highest volume setting. Now if I charge my cellphone at the same time its down to more like 4 hours, so I always bring a 2nd battery. I wish I would have just bought a hi-capacity battery instead of 2 batteries and a charger because the radio is actually a charger when you plug it in.

Battery is supposed to last about 8 hours but can vary depending on volume, etc. I haven't really pushed it that far to see if it will last that long.

I pretty sure it's at least 8 hours. I use mine for the better part of my 12 shift at work and if it ever dies, it's right before I leave work. I'm sure volume level has s major part in this.

The battery will last for 10 hours, but only when kept at a moderate volume. If you crank the volume up near max, the battery will last about 5 hours.

yes, the batteries works very well, I can tell after 4 days when the batteries are getting low the sounds are not as loud.
